In August 1973, Thero Wheeler escaped from Vacaville; friends, perhaps from the nascent SLA, provided transportation and a change of clothes after he walked away from the complex. In a later prison interview, Wheeler said friends who aided his escape were "well-connected". Close friends say Wheeler split with the SLA in October 1973 because of their plans for violent tactics (as in the
Marcus Foster murder) and he argued with DeFreeze and others competing for leadership. He called DeFreeze a "drunken fool" and was threatened with death. Reported but mistaken sightings of Wheeler around the time of the Hearst kidnapping led to speculation that he was still involved, and to the notion that he was one of those killed in the Los Angeles shootout and fire. On 4 May 1974, an article in
The Pittsburgh Courier quoted Wheeler's girlfriend
Mary Alice Siem. It reported material published in
The San Francisco Examiner. She said that they had left the SLA due to death threats from DeFreeze. :Mary Alice Siem, 24, Redding, Calif., told authorities she and Thero Wheeler, 29, unofficially identified two months ago as a possible suspect in the
Hearst kidnapping, left the terrorist organization last October because they disagreed with the SLA's plans for violent tactics. :Miss Siem ... said she and Wheeler, who were living together, attended about 20 SLA meetings. ... :On one occasion she said she was threatened at gunpoint by DeFreeze, Miss
Soltysik, and Miss
Perry, but Wheeler intervened. When they left the SLA, she said she and Wheeler were robbed of $600 by the other members. :According to the
Examiner, whose president and editor is Miss Hearst's father, Miss Siem told authorities that she and Wheeler left the SLA because Wheeler was opposed to the violence espoused by DeFreeze. :She said their departure took place in October, a month before the fatal shooting of Oakland Schools Superintendent
Marcus Foster, for which the SLA claims responsibility, and four months before Miss Hearst was kidnapped. But after
Patty Hearst was kidnapped, a number of eyewitnesses contributed to
identikit composite sketches of the men they had seen. The drawings appeared to resemble DeFreeze and Wheeler so closely that police soon attached names to these sketches. They mistakenly identified Wheeler as a suspect in the kidnapping. ==Later life==
